The interrelationships between selected physiological, metabolic and hormonal variables were investigated in active and sedentary middle-aged males during consecutive periods of rest, graded exercise on a bicycle ergometer, and recovery. Venous blood samples were drawn during each phase of the activity which was performed in the post-absorptive state. Data were analysed using correlational and factorial analysis techniques, and further evaluated by discriminant function procedures. Significant correlational relationships were evident among physiological, metabolic and hormonal variables, and factor analysis identified four factors at each phase of activity which accounted for as much as 69% of the common extracted variance. These factors described physiological function and hormone-metabolite behaviour during each phase of activity. Discriminant function allowed fitness classification of subjects using only the hormone-metabolite data, thus identifying specific biochemical correlates of the fitness groupings which had been established by physiological criteria alone.
在连续的休息期、在自行车测力计上进行的分级运动期和恢复期，对活跃的和久坐不动的中年男性的选定生理、代谢和激素变量之间的相互关系进行了研究。在吸收后状态下进行的活动的每个阶段采集静脉血样。使用相关分析和因子分析技术对数据进行分析，并通过判别函数程序进行进一步评估。生理、代谢和激素变量之间存在显著的相关关系，因子分析在活动的每个阶段确定了四个因子，这些因子占共同提取方差的69%。这些因子描述了活动每个阶段的生理功能和激素-代谢物行为。判别函数仅使用激素-代谢物数据就可以对受试者进行体能分类，从而确定仅通过生理标准建立的体能分组的特定生化相关性。
